LOOM FOR WEAVING ORNAMENTAL FABRICS.

SPECIFICATION forming part of Letters Patent No. 762,525, dated June 14,1904.

Application filed May 21, 1903. Serial No. 158,195. (No model.)

To aid w/wm it may concern.-

Be it known that 1, WILLIAM G. HARTLEY, a resident of Amesbury, in thecountyof Essex and State of Massachusetts, have invented certain new anduseful Improvements in Looms for Weaving Ornamental Fabrics; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and

to the letters of reference marked thereon,

which form a part of this specification.

This invention relates to looms for weaving ornamental fabrics.

The object of the invention is to do away with the ordinary wiredoup-heddles in weaving this class of fabric and form the loop by thesimple method of carrying the loop-thread over a stationary finger bymeans of a flexible reciprocating looper or carrier.

This invention is fully described in this specification and illustratedin the accompanying drawings.

Figure 1 is an end sectional diagrammatic view showing parts of the loomand the relative position of the new device to the usual parts lookingin. the direction of one end of the loom. Fig. 2 is a diagrammatic viewillustrating the connections of the frames to,

which the carriers are attached and the jacklevers of a (lobby-head,which are arranged to operate said frames. Fig. 3 is an enlarged detailof one of the fingers or guide-hooks which guides the flexible carrieras it conducts the binding-thread over the warp-threads. Fig. 4illustrates one form of fabric which may be woven with this attachment.

Referring to the drawings, Fig. 1 represents the weaving as being doneon plain cloth. In this figure, A is the usual yarnbeam that carries thewarp-threads from which the ground fabric is Woven. B B are the heddlesorharnesses that control the warpthreads, and D D are two frames similarin construction to the heddle-frames, but are for the exclusive purposeof engaging the ends of the carriers E, and through which said carriersare all actuated in time with each other.

The principal feature of this invention is the stationary finger or hookand my improved method of carrying the loop-thread,

by means .of said finger, over a predetermined number of warp-threads bya flexible looper or carrier E. This carrier is constructed of aflexible cord, wire, leather, or any suitable material and has an eye 0at or near its middle portion. The bight of the carrier is passed overthe loop-fingcrO and one end secured to the lower bar of each of theframes D and D. This loop-finger or hook C is a short piece of flat wirelocated near the harnesses and preferably fixed just above the shed atits extreme upward stroke. These fingers project longitudinally forwarda short distance and may be rigidly supported in position by the tworods 0 c, to which they are secured, or by any other convenient method.Any number of these fingers may be employed, according to the patterndesired to be woven. I,

The two framesD and D are actuated to reciprocate alternately and intime with each other. Any suitable meanssuch as cams, jacquardmechanism, or dobby-head-may be employed to operate these frames. InFig. 2 I illustrate the frames as being controlled by the jack-levers FF, which are attached to any ordinary (lobby-head, the action of whichjacks may be controlled in the manner well known by those skilled in theart to which this device appertains. In order to produce the requiredresult, I prefer to use the first and second jacks to operate frame Dand the third and-fourth jacks to operate frame D, thus using twojack-levers for each of the carrierframes. My method of connecting theframe to 'thc jack-levers is a cord (Z or other suitable flexibleconnections attached to the bridle (Z on the frame. On the upper end ofthis cord is a pulley f, through which is rove a cord f, with its twoends fast to the jacks F and F, respectively. Each of said frames isalso connected underneath in a similar manner to the lower arms of saidjack-levers.

The loop or binding-thread G is led from a spool H on the rear of theloom over a spring-tension bar g down in front of the harcording to thestyle of goods desired.

nesses and through the eye w in the looper or carrier E. Thenceit runsthrough the reed R to the ground fabric J, to which it is secured. Bymeans of the looper or carrier this thread is carried over any desirednumber of warpthreads, according to the pattern to be woven, andtransferred alternately from one side of the loop-wire O to the otherside and bound down by the passing of the shuttle over it. To producethis open-work or lace effect, the binding-thread is led up over theshort finger C and carried over the required number of \ViU'P-tlllOfltlSby the flexible carrier E and down on a lever with the. lower shed andproperly bound in place by the passing through of the shuttle carryingthe weftthread. This binding-thread is then beat up with the weft-threadby the reciprocating .reed R and drawn up tightly around thesewarpthreads, over which it has been carried, binding them tightlytogether into a strand or cord. The binding of these warp-threadstogetherleaves open spaces between the remaining warp-threads and thosebound together, forming an open-work or lace effect in the fabric. Thisstrand or cord of warp-threads is firmly held in place by theweft-threads in the fabric. This open-work may be woven in the fabric instripes as close together as desired by simply regulating the number offingers, corresponding carriers, and bindingthreads. Any variety ofcolors and styles of weaves may be produced by this simple mechanism.

Any number of flattened wires C and corresponding binding-threads G- maybe used eitherin groups or otherwise, and any number of harnesses orshuttles may be employed, ac-

The fabric as fast as woven is drawn over the breast-beam S by thetake-up motion. (Not shown.) Only enough of the loom is shown toillustrate the operation of my invention.

The mechanism for operating the different parts is not shown ordescribed, as they are all well known, and no particular way ofoperating the same is claimed. Any of the several varieties of looms maybe employed for this work that may upon trial be found advisable.

The operation of my device is further explained as follows: The flatloop-forming fingers C are supported and fixed at one end and extendforward a short distance. The flexible looper or carrier above describedis attached to two frames, which are used exclusively for the operationthereof. In the (lobby-head shown 1 use two jack-levers to operate eachof the two heddle-frames, each frame being drawn alternately up and downby the movement of the jack-levers because of the connections betweenthe top and bottom of each frame with each arm of the jacklevers. Theseconnections are effected by attaching each end of a flexible cord tosaid arms, with the bight of said cord engaging a pulley held on the endof strap leading from one of the harness-frames. 1n operating thesejack-levers thus connected by holding one jack up and letting one downthe frame is in its center position, and when both jacks are either upor down the frames are in a corresponding position. The binding-threadis led from a spool on the rear of the loom over a tension-bar, carrieddown in front of the harness, threaded through the eye of the carrier,and led through the reed to the groundwarp, into which it is secured bythe laying of the weft-threads. By properly pegging the links of thechain in the dobby-head this binding-thread may be held up on top of thewire any number of picks, whereby any desired length of fabric may bewoven before said binding-tln'eads will be caused to cross the warpthreads engaged thereby, or the thread may be drawn down on each side ofthe wire and held as long as desired, in which position thebinding-thread lies on the back of the web, or this thread may becarried up and down on the same side of the wire, thus forming a plainweave Without binding the warp.

It will be observed that by the use of my device only two harnesses arerequired to weave any pattern, while by the old method three or more areemployed. By running the binder-threads in front of the harnesses thework is much more accessible and easier to operate. This arrangementalso causes less friction and wear than by the old method, where thesethreads had to be passed through the heddles. One very important featureis my carriers at all times remain in their place between thewarp-threads and are sure to work without catching and becoming easilydestroyed, as has heretofore been the case by the use of the old methodin doup-weaving. The wear of these carriers is reduced to the minimum inworking back and forth over the fingers or guides as they are raisedfrom and practically carried over said guide-lingers by the tension ofthe binder-threads which engage them.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a loom of the character described, a short rigidly-supportedoutwardly-extending finger or guide located approximately in line withthe warp of the open shed, means by which the binding-threads may becarried over said finger or guide and any predetermined number ofwarp-threads, and means located beyond the end of said guide or fingerand adapted to beat up said binding-threads when said binding-threadleaves said finger.

2. In a loom of the character described, a short rigidly-supportedoutwardly-extending guide or finger located approximately in line withthe warp of the open shed, means by which the binding-thread may becarried over said guide or finger and any predetermined number ofwarp-threads, and a reciprocating reed located beyond the end of saidfinger or guide and adapted to beat up said bindingthreads when saidbinding-thread leaves said finger or guide.

3. In a loom of the character described, a short outwardly-extendingguide or finger located approximately in line with the warp of the openshed, a flexible carrier arranged to carry the binding-thread over saidguide or finger and any predetermined number of warpthreads, and meanslocated beyond the end of said guide or finger and adapted to beat upsaid binding-threads when said binding-thread leaves said finger orguide.

I. In a loom of the character described, a guide or finger located nearthe harness, skeleton frames through which the warp-threads are free topass, means for reciprocating said frames, aflexible member connected atits ends and passed over said guide or finger, said flcxible memberserving as a carrier for the binding-thread, and means located beyondthe end of said guide or linger and adapted to beat up thebinding-threads when said binding-thread leaves said guide or finger.

5. In a loom of the character described, a framework, rods rigidlysupported thereby, a short, outwardly-extending guide or finger rigidlysupported by said rods and located approximately in line with the warpof the open shed, and means by which the binding-threads may be carriedover said guide or finger and any predetermined number of warp-threads.In testimony whereof I have hereunto set my hand this-19th day of May,A. D. 1903.
